Extraordinary claims require extraordinary evidence, on both counts. If you're suggesting a local news station was literally paid to put out a news story about noise-related rollercoaster nuisances... that's quite the claim. No idea what you're getting at re: the "source," because, of course. The sources are the neighbors complaining.
As for the spoiler story... everyone's source there seems to be some variation of "trust me" or "I heard it from some people who told me to trust them." It screams telephone game.
